When Apple released iOS 9.3 there have been some notable bugs that have created issues for some users after they installed the latest update. The main issue was with iPad Air and earlier models required entering the Apple ID and password to used to set-up the device to complete the software installation. If for some reason, iPad owners couldn’t remember their password, their devices were stuck in an inactivated state until they could either recall the password or were able to reset it. As a result, Apple temporarily disabled updates for the older iPads (and iPhones older the the 5s) until they could release an updated version of iOS 9.3 that didn’t create the same issues. Apple has created a support document for those iPad owners who are currently stuck in the activation state.
